Yes, I find CUDA on my machine to be much faster than without it, but it's
an in-between situation because only some effects can take advantage of CUDA
processing (according to Adobe Help), thus there remain situations where
playback is not smooth without pre-rendering. Adobe says they can't reliably
predict success with CUDA, and for those situations they color the render
bar yellow (to signify "hopefully"?)
Worse, CUDA sometimes can't handle panning/scaling of large photos and will
crash the system (even in CS5 and CS5.5) - the work around is to turn the
Mercury Playback Engine off and use software rendering only.
Someday the graphics hardware and software people might get to a point where
even the yellow bar goes away!
And another help would be for the Global Warming advocates to invent a
gigantic fan to blow our ~100 degree temps over the next 2-3 days down your
way to help with your 7 degrees!

Lee,
Isn't the whole idea of a fast computer/ graphics card etc. to preview
the timeline without
rendering first?
I am forced to do that with my vintage computer which takes extra time
being no problem
for an old toppie like me but surely professionals don't want to
spend/waste that time.
